I've heard bad things about call quality with VoIP.

We have, too. We're happy to say that call quality, overall, has improved with VoIP and is now as good as or better than call quality on a land line. Most call quality issues are caused by network connectivity issues which have been solved by improved technology. Didn't understand that? Neither did I. Basically, both VoIP companies and consumers have access to better, faster Internet networks. This means that calls sound better. Did the call quality on your latest VoIP call stink? Look for your VoIP provider and write a review.
